More earthquakes in Seattle? A major fault runs beneath downtown Seattle. Faults are related to earthquakes and we have excellent evidence for a magnitude 7.0 or greater earthquake on the Seattle Fault 1100 years ago. Alki Point, Restoration Point (Bainbridge Island) and tsunami evidence near Everett are all connected to the 900 A.D. Seattle Fault earthquake.The 900 A.D. quake produced 21 feet of sudden uplift at some locations. The potential for that type of extreme ground shifting under our biggest city has scientists, engineers and emergency planners concerned. What can you do to prepare? Be ready for one week of self-sufficiency in the event of a major earthquake.
